Rutter et al demonstrated the importance and effects of adopting orphans at different ages, which was directly related to their rate of recovery. A full recovery could be made if adoption occurred before the age of 6 months. This includes both emotional and intellectual developmental recoveries. These conclusions were supported by the Bucharest Early Intervention project carried out by Zeanah et al, who demonstrated that 65% of their sample of 95 orphans displayed signs of disorganised attachments, compared to only 20% of the healthy, non-deprived control group.
